Drawing a Plane

Hi! I working on a bsp compiler and need a function to draw a plane with the fallowing equation N*P - d = 0 Also there is the type TPlane with this members: Type TVector Field X : Float Field Y : Float Field Z : Float ... End Type Type TPlane Field Normal : TVector Field Distance : Float ... End Type I know, a plane has a infinity size, but I need only to draw a part of it. Like 100 * 100 unions. My first advisement was, to convert from to set lambda and mu to -50;50, 50;50, 50;-50 and -50;-50 and draw it with GL_QUADS. But I haven't a equation to convert or know if this will working with lambda and mu. cu olli |

You could probably just create a matrix for the normal of the plane, load it, then draw a flat quad. |

Thats a idea, but how? How I can create a matrix from a vector? I can build a matrix by using a quanternion by using a vector but in addition a angle. cu olli |
